Thank you all for your feedback! I think the AHUs were designed using extreme temperature outdoor air conditions (instead of extreme moisture) and too high of a dew point of the leaving air. These resources were helpful too:

-ASHRAE dehumidification...
It's a dormitory. There are essentially three wings separated by two atriums. Hot/humid climate up to 114F DB and 88 WB in the summer.
I don't have any data on the FCUs yet, but I've requested the tech specs. The measured temperatures in the rooms during the summer was between 73-77F with RH...
Thanks for the feedback, I appreciate it!
Yes, SHR at the FCUs was modeled as 0.9. Their modeling didn't consider any latent load from outdoor air (I guess they figured they had it covered by the AHUs).
I calculated the load at the AHUs using the sensible design day and came up with a coil...
Hello all, I recently started working in an area with high sensible and latent loads. I am trying to provide a solution for a previously installed system in a recently commissioned building where they are having condensation issues. The building was designed with FCUs to provide cooling for the...
